Subject[PATCH 0/5] kill ptrace_{get,put}_breakpoints()
Hello.

Kill ptrace_{get,put}_breakpoints and task_struct->ptrace_bp_refcnt,
9899d11f "ptrace: ensure arch_ptrace/ptrace_request can never race
with SIGKILL" made this all unneeded.

Benjamin, Paul, arch_dup_task_struct()->flush_ptrace_hw_breakpoint(src)
on powerpc looks "obviously wrong". Don't we need

- flush_ptrace_hw_breakpoint(src);
+ dst->thread->ptrace_bps[0] = NULL;

?

Oleg.
